The I/50 is designed to be easy to use, and has three controls on its top panel - Power, Input, and Volume. Two LexieTubes® provide display information for input selection and volume. Two matched pairs of 6550WE vacuum tubes, along with three 6922 tubes, stand in front of the perforated transformer cover. Three single-ended inputs and one XLR input provide connectivity for most systems, alo...[more]

The Krell Illusion preamplifier is a dual monaural circuit design with the left and right channels afforded their own power supply regulation and individual full chassis sized boards. All signal gain is realized in surface mount topology using proprietary multiple-output current mirrors with nearly 500 times the open loop linearity of other designs. 1.5 MHz open loop bandwidth in a zero feedbac...[more]

Circuitry Highlights: the Illusion II preamplifier is a dual monaural design with the left and right channels afforded their own power supply regulation and individual circuit boards. All signal gain is executed with surface mount technology using proprietary multiple-output current mirrors with nearly 500 times the open loop linearity of other designs. Featuring 700 kHz bandwidth in a zero fee...[more]

The Inspiration 2 Integrated features an LCD touchscreen for easy access to every adjustment, with an elegant, machined aluminum remote control for key functions. Thanks to the resistor-ladder volume control, digitally controlled through a smooth-spinning volume knob on the front panel, the Inspiration 2 Integrated achieves precise channel matching impossible with potentiometers. The new Co...[more]

The Inspiration 2 Stereo and Mono use the same Line Stage Gain Module input stage found in our top amplifiers. Hand-matched, low-noise transistors combine with a servo circuit that corrects any signal balance inconsistencies. The Inspiration 2 amplifiers’ Constellation Link interface connects to Constellation amplifiers to remove one amplification stage from the signal path, resulting in ...[more]

The Line Stage Gain Module employs fully balanced, mirror-imaged circuits made with hand-matched, ultra-low-noise transistors. A unique servo circuit monitors the signal balance and corrects for even minute inconsistencies. If you use a Constellation Audio amplifier, you can feed the Inspiration 2 Preamp’s output to the amp’s Constellation Switched-Mode Power Supply (C-SMPS) pro...[more]
